Eclipse Over America
On August 21, 2017, millions of Americans will witness the first total solar eclipse to cross the continental United States in 99 years. As in all total solar eclipses, the moon will block the sun, revealing its ethereal outer atmosphere its corona in a wondrous celestial spectacle. While hordes of citizens prepare to flock to the eclipses path of totality, scientists, too, are staking out spots for a very different reason: to investigate the secrets of the suns elusive atmosphere. During the eclipses precious seconds of darkness, they will shed light on how our sun works, how it can produce deadly solar storms, and why its atmosphere is so hot. NOVA investigates the storied history of solar eclipse science, and joins both seasoned and citizen-scientists alike as they don their eclipse glasses, tune their telescopes, and behold the Eclipse Over America.

Death Dive to Saturn
Almost everything we know today about the beautiful giant ringed planet comes from Cassini, the NASA mission that launched in 1997 and arrived at Saturn in 2004. Since then, the spacecraft has been beaming home miraculous images and scientific data, revealing countless wonders about the planet, its rings and many moons including some that could harbor life. As the mission approaches its final days in 2017, it attempts one last set of daring maneuvers diving between the innermost ring and the top of Saturns atmosphere. Aiming to skim less than 2000 miles above the cloud tops, no spacecraft has ever gone so close to Saturn, and hopes are high for incredible observations that could solve major mysteries about the planets core. But such a daring maneuver comes with many risks and is no slam dunk. In fact, slamming into rocks in the rings is a real possibility. Join NASA engineers for the tense and triumphant moments as they find out if their bold re-programming has worked, and discover the wonders that Cassini has revealed over the years.

Secrets of the Shining Knight
A knight in shining armor may sound like a character out of a storybook, but once upon a time, knighthood was serious business, and for countless medieval fighters, their armor was what stood between life and death. But what was it really like to live beneath the metal? How was that shining armor crafted and how strong was it? Could it withstand impacts from the most lethal weapons of the day, including crossbows, muskets, and primitive hand guns? NOVA challenged blacksmith Ric Furrer and master armorer Jeff Wasson to recreate parts of an elite suit of armor originally manufactured in King Henry VIIIs royal arsenal. We trace their successes and setbacks from start to finish as they rediscover centuries-old metalworking secrets, then put their new armor to the ultimate test against a period musket!

Ghosts of Stonehenge
Stonehenge is the grandest and most enigmatic of Europes prehistoric monuments, and has inspired countless theories to explain who built it and why. Was it an ancient cathedral or burial place, or even a Stone Age observatory or computer? Over the last decade, fresh answers have come from an ambitious program of research, including the first scientific study of human remainsthousands of fragments of cremated men, women, and childrenburied at the site 5,000 years ago. In this Stone Age detective story, archaeologists analyze the bones and piece together tantalizing details of the elite families who presided over Stonehenge. Remnants of huge feasts that fed the laborers at the site have come to light, including evidence that they traveled from far corners of the British Isles to raise the stones and celebrate the winter solstice. Yet Stonehenges place as a centerpiece of ancient culture was not to last. Join NOVA as we reveal intimate details of the Stonehenge people and why their power began to fade soon after they raised the mighty stones.

The Forbidden City’s Seismic Secrets
The Forbidden City is the worlds biggest and most extravagant palace complex ever built. For five centuries, it was the power center of imperial China and survived wars, revolution, fires, and earthquakes. How did the Ming Emperors workforce construct its sprawling array of nearly 1,000 buildings and dozens of temples in a little over a decade? How were stupendous 250-ton marble blocks moved across many miles to reach the site? And how did fantastically intricate woodwork, all fastened without nails or glue, enable the palaces to survive hundreds of earthquakes, including recent ones that obliterated nearby modern structures? To find answers, NOVA joins a team of master craftsmen who build a scale model of a typical palace in a seismic lab, then subject it to simulated earthquakes to shake out the secrets of how the Forbidden City has withstood centuries of violent tremors.

NOVA follows a team of volcano sleuths as they embark on a worldwide hunt for an elusive volcanic mega-eruption that plunged the medieval earth into a deep freeze. The mystery begins when archaeologists find a hastily dug mass grave of 4,000 men, women, and children in London. At first they assume its a plague pit from the Black Death, but when they date the bones, theyre a century too early. So what killed off these families? The chronicles of that time describe a run of wild weather that devastated crops and spread famine across Europe. NOVAs expert team looks for the signature of a volcanic eruption big enough to have blasted a huge cloud of ash and sulfuric acid into the atmosphere, which chilled the entire planet. From Greenland to Antarctica, the team finds telltale fingerprints in ice and soil layers until, finally, they narrow down the culprit to a smoldering crater on a remote Indonesian island. Nearly 750 years ago, this volcanos colossal explosion shot a million tons of rock and ash every second into the atmosphere. Across the globe, it turned summer into winter. What would happen if another such cataclysm struck again today?

The Great Hurricane of 1780 took nine days to blast its way across the Caribbean, killing at least 20,000the highest known death toll of any single weather event in history. What made this superstorm so deadly? To reconstruct its epic scale and investigate what made it so devastating, NOVA joins historians and storm sleuths as they track down clues in eyewitness chronicles, old ruins, and computer simulations. Their evidence points to a truly terrifying, 300-mile-wide stormwith wind speeds probably exceeding 230 miles an hour and 25-feet storm surges that demolished everything in their path. But just how unusual was the Great Hurricane? Diving into sinkholes off Barbados and squirming into caves in the Yucatan, NOVAs experts recover traces of tempests stretching back over more than 1,000 years. The picture they paint is disturbing: mega-hurricanes were not only more frequent in the past but are likely to strike again in our near future, as climate change warms the oceans and fuels more intense hurricanes. Were the deaths and damage inflicted by storms like Hurricane Sandy a prelude to far more devastating disasters?

All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? Over a vast expanse of Washington State called the Channeled Scablands, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky; a cliff carved by a waterfall twice the height of Niagara; and potholes resembling ones scoured out by rivers today, but ten times bigger. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the worlds top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland andimprobablyon the seabed of the English Channel, where hundreds of thousands of years ago, another deluge smashed through a land bridge connecting Britain and France and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hoursand similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.
